# Understanding Ball Mill Sizing

### Ball Mill Application and Design

Ball mills scale up well and in fact improve in performed with increasing size. Ball mills are available in sizes from laboratory scale (also called milling jars) of 0.1 usg to large 5,000 gallon mills. Ball mills are available in various contact materials to accommodate contamination and wear requirements.

### The effect of ball size on mill performance - ScienceDirect

The specific rates of breakage of particles in a tumbling ball mill are described by the equation S i = ax α i (Q(z), where Q(z) is the probability function which ranges from 1 to 0 as particle size increases.This equation produces a maximum in S, and the particle size of the maximum is related to ball diameter by x m = k 1 d 2.The variation of a with ball diameter was found to be of the form ...
